David Morrissey in 'Thorne: Sleepyhead'
Encore David Morrissey in 'Thorne: Sleepyhead'

Versatile Liverpool-born actor David Morrissey has taken roles ranging from prime minister-to-be Gordon Brown in Stephen Frears' "The Deal" to the Duke of Norfolk in "The Other Boleyn Girl" to the object/victim of Sharon Stone's affections in "Basic Instinct 2." But it's policemen for which he seems to have a particular affinity, playing cops good, bad and guilt-ridden in multiple British television series and the "Red Riding" film trilogy. The character of Tom Thorne, whom he plays in a pair of three-part miniseries, "Thorne: Sleepyhead" June 12 and "Thorne: Scaredy Cat" June 13 (both Encore, starting at 9 pm), is something unique, a detective who often seems in danger of getting pulled into his cases.

Investigating first a sadistic criminal whose aim is to leave his victims with locked-in syndrome (like Jean-Dominique Bauby, protagonist of "The Diving Bell and the Butterfly") in "Sleepyhead," and then a pair of serial killers that may be working in tandem in "Scaredy Cat," Thorne gives himself over to his work in a way that's almost as troubling as the crimes he's trying to solve. Morrissey's a great fit for the character -- he shares the screen with talent that includes Eddie Marsan, Aidan Gillen, Natascha McElhone and Sandra Oh -- and we're not the only ones who thought so, as you'll see below.

The actor's also about to become a much more familiar face to U.S. TV audiences -- it was announced in February that he'll be taking on the role of the infamous Governor on the new season of "The Walking Dead," a villain far more dangerous than the zombies the characters have to fend off. Indiewire caught up with Morrissey on the phone shortly before he headed off to start work on the AMC series.

Thorne: Sleepyhead 2
You aren't just the star of the "Thorne" series, you also served as a producer. How did "Sleepyhead" and "Scaredy Cat" come together?

I was doing a film in New Zealand called "The Water Horse," which was rife with green screen. For an actor, that can mean you have a lot of time on your hands, so I raided the bookshops. One of the books I picked up was "Sleepyhead," by Mark Billingham. I really enjoyed it. I Googled him and came across an interview he did, where he said, "If the books ever came to the screen, I couldn't think of anybody better than David Morrissey to play the role of Tom Thorne." I thought, oh, well, that's fun. I got in touch with him, and when I got back to the U.K. I bought the rights to the novel. Sky came on board and they were very supportive, and we made the series.

What was it about the character of Thorne that appealed to you?

In that particular book, it was the idea of a man who was married to his job, who only comes alive when he's working -- he has no other life, really. And he recognizes that that isn't a healthy situation, but he's slightly stuck. This case comes along, this girl who was deliberately put into a comatose state by a killer who wants to freeze people. That's a terrible crime for anybody, but for Thorne it has this resonance, it becomes a personal crusade for him. That connection with the victim was something I hadn't really seen played out before. I love the fact that Thorne has this massive empathy for certain victims -- in the second series, "Scaredy Cat," it's a young boy who's seen his mother killed.

I read a lot, and I'll read thinking, 'Would this make a film? Would this be a good character?' I know a book is good when those questions stop hitting my head, when I just get involved in the story. With "Sleepyhead," it was absolutely that -- I just gave into the fact that this was a great story. It was afterward that I had to start thinking about how to put it on screen.

In addition to being a novelist, Mark Billingham has also worked as an actor and has written for television. Did that make adapting his books easier?

He was very amenable. His wife is a TV director, so he'd been involved in the world a lot. There were certain things in the characterization and story that he wanted to keep hold of, and nine times out of ten they were things that I wanted to keep hold of as well. The great thing was that he recognized that if you're going to get a screenwriter involved, you have to be able to give them license to go away and discover it themselves, and he did do that. Then Stephen Hopkins came in to direct the show. He'd done "24" and "Californication," and I'd worked with him before on a film called "The Reaping" that we'd done down in Louisiana. He's a wonderful director, and he came and added that next element to it -- this great pace and look and design.
